Result: add __bool__ function

[esunar]

We can add the __bool__ function to the Result class as a fauture for use in a logic condition.

def __bool__(self):
    return not self.empty

Than we can use it like this:

return result or Result(Severity.OK, 'Minimum juju version check passed.')

instead of this:

if result.empty:
    result.add_partial_result(Severity.OK, 'Minimum juju version check passed.')

return result
